- Fix: installing FontAwesome Pro (`POST /admin/content/iconpacks/install`, the buttons of the dialog *Emoji a ikony*) ended with `OutOfMemoryException` in an API pod with the 512 Mi limit. `FontAwesomeInstaller` held the whole downloaded tarball in memory (several copies, one of them reachable for the whole install) and `IconPack.Save` built a copy of all icons before writing. The tarball now goes to a temporary file in the install directory (`download-*.tgz.tmp`, removed as soon as it is processed, also after an error) and `Save` writes the icons one by one with `CompressionLevel.Optimal`; the JSON format is unchanged, so packs stay readable by older versions. Installing Pro 7 peaks at ~120 MB instead of ~440 MB and takes about 3 s of CPU (it fits a 128 MB heap). A loaded Pro 7 pack takes ~53 MB in every process that loads it (API replicas, editor, MCP). - ReportServer: the install of an icon pack keeps running when the client disconnects (it has its own limit of 15 minutes, `504` when exceeded); before, the finished work was discarded when the caller had given up. `FontAwesomeInstaller` in the API now logs its phases (download size and time, number of icons, save). - Template editor: the install of an icon pack waits up to 10 minutes (own client `IconPackInstallClient`; the other calls to the API wait 30 s, which ended the install with an unhandled error), the dialog *Emoji a ikony* shows a spinner with the elapsed time, and a timeout is a message in the dialog.
